+Adds a pattern to a font set.  Note that the pattern is not copied before

+inserted into the set (due to allocation failure). Otherwise returns FcTrue.

+This function is useful for diagnosing font related issues, printing the
+complete contents of every pattern in <parameter>set</parameter>. The format

+If <parameter>trim</parameter> is FcTrue,
+elements in the list which don't include Unicode coverage not provided by

+The returned FcFontSet references FcPattern structures which may be shared

+The FcFontSet returned by FcFontSetSort is destroyed by calling FcFontSetDestroy.
